Review Circular hollow sections for the Ø 88.9 × 4 mm specification. Check material grade, dimensions, inspection documents and delivery requirements before requesting a quotation.
Geometric estimates exclude rolling tolerances, coatings and process losses; hollow and rolled-section references include their own section-table basis. Calculated bar weights use unrounded mass. Values are not measured shipment weights. Confirm length, grade, manufacturing route, packing and supply in the offer; the existing image illustrates the product family.
Ø 88.9 × 4 mm: outside diameter 88.9 mm and nominal wall thickness 4 mm. Reference mass approximately 8.38 kg/m (EN 10219 reference geometry); calculated weights are 50.28 kg for 6 m and 100.56 kg for 12 m. Request 6 m, 12 m or agreed cut lengths, subject to confirmation. Actual weight depends on dimensional tolerances and the supplied section; confirm the mill table and weighing basis. Ø 88.9 × 4 mm

Standards and applicability
Keep EN 10219 cold-formed welded and EN 10210 hot-finished routes separate. Numeric S355J2H rows below are EN 10219 references for t ≤ 16 mm, not automatic EN 10210 or S355NH data. The tensile band changes below 3 mm. Elongation is reduced from 20% to 18% where D/t < 15 for CHS or (B+H)/(2t) < 12.5 for RHS/SHS; below 3 mm confirm gauge length and specimen width. The 27 J at −20°C reference requires the applicable impact-testing and subsize rules. Confirm grade, wall, corner geometry, weld inspection and certificate for the actual route.

Selected percentages by mass and test values are reference requirements within the stated scope, not the actual heat analysis or a complete specification. A dash means no value is declared here, not zero. Compare the offered heat and test results with the applicable specification and inspection document. If EN 10204 type 3.1 is required, agree document availability, heat traceability and test scope before ordering.
Inspection and export enquiry
Send the exact product, size, full grade and standard edition, delivery condition, quantity, test requirements and named destination. Confirm cutting, coating, bundle or coil mass, protection, unloading and the Incoterms delivery point in the quotation. The destination guidance below supports port and inland comparisons; it does not confirm local stock or a fixed price.
Size specifications: Circular hollow sections Ø 88.9 × 4 mm
Ø 88.9 × 4 mm: outside diameter 88.9 mm and nominal wall thickness 4 mm. Reference mass approximately 8.38 kg/m (EN 10219 reference geometry); calculated weights are 50.28 kg for 6 m and 100.56 kg for 12 m. Request 6 m, 12 m or agreed cut lengths, subject to confirmation. Actual weight depends on dimensional tolerances and the supplied section; confirm the mill table and weighing basis. Ø 88.9 × 4 mm
Choosing this specification
For Ø 88.9 × 4 mm, check outside dimensions, wall thickness, corner geometry and end preparation against the fabrication drawing. Connection fit and section properties require the exact profile; nominal envelope dimensions alone are insufficient. At nominal geometry and 7850 kg/m³ steel density, the reference is 8.375 kg per metre. This calculation excludes tolerances, coatings, corner radii and process losses; it is not certified shipping weight or a load rating. Compared with Ø 101.6 × 4 mm, the nominal geometric reference is 13.0% lower on the same basis. This comparison supports quantity planning; it does not establish interchangeability.
Buying Circular hollow sections Ø 88.9 × 4 mm and requesting a price
The price for Circular hollow sections Ø 88.9 × 4 mm depends on the material specification, quantity, production or processing requirements, inspection, packing, freight and delivery schedule. Compare offers on the same technical specification and delivery basis; confirm availability and quotation validity before ordering.
For buying and price enquiries for Circular hollow sections Ø 88.9 × 4 mm, specify your delivery destination: Georgia (including Tbilisi), Turkey (including Ankara and Istanbul), the United Arab Emirates (UAE, including Dubai), Kuwait, Oman or Qatar. Send the required quantity, grade or chemical analysis, dimensions and inspection scope. Freight, delivery terms and shipment timing affect the quotation; supply options and destination documentation require confirmation before an order is agreed.
